Sainsbury’s is taking on Tesco’s double Clubcard points scheme with a new investment in coupons handed out at the till.

The retailer said it would use the Nectar card database to target shoppers with products relevant to past purchases, in its biggest investment in customer loyalty since launching the Nectar scheme in 2002.

The new scheme will also reward customers without a Nectar card by giving out coupons based on what was in shoppers’ basket that day.

The move comes just weeks after Nectar managing director Jan-Pieter Lips told The Grocer there would be no response to Tesco’s decision to double Clubcard points.

Tesco has claimed that doubling loyalty points has drawn in thousands of new customers.

Over 60 brands, including Unilever, Proctor & Gamble and Heinz, have signed up to the scheme, offering discounts of up to 20%.
